Application tiled September 29, 1906. Serial No. 338,704.

To all ll'lm/ny if muy mur/'rnc 55 conveyers in section. Fig. 7 is a detai. peri place to place.

Be it known that I, PETER MCNERNEY, a citizen of the United States, residing at Lake Einio, in the county of Washington and Stale of Minnesota, have invented new and useful improvements in Apparatus for Unloading Platform-Cars, of which the following is a specification.

This invention relai es to apparatus for unn loading platform-cars' and one of the principal objects of the same is to provide ellicient. means for delivering gravel or dirt from platform-cars at the required distance at opposite sides of tlxe track.

Another object. of m invention. is to provide reli:` and clik-isnt means whereby the contents of platform-cars may he deposited at the opposite sides of the railroa l-track at the required distance from said cars and to provide means whereo \l the unloading appa- Iatus may be drawn fr-'nn one platform-car to the other the full length of the train.

ftill another object of me invention is to ovide an apparam.-` mounted upon roliers fo be drawn over platform-cars to discharge the contents of said cars upon laterally-extending eonvevers to deposit the laad upon one or both sides of the traol'; ai, sane distance f1 om the cars.

Another object of in v invention is to provide a porta-ble unloading device to be moved from car to car for unloading the contents thereof at some dist ance upon opposite sides of the track and to provide means for lifting the convevcrs up out of operative position and swinging them into alinementwith the cars when the machine is to be conveyed from The foregoing and other objects ma)r be attained b v means of the construction illust-rated in the accompanying drawings, in which Figure 1 is a side eevation and partial section of an unloading apparatus constructed in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal section of the same. Fig. 4 is a transverse section, on an enlarged scale, showing the turn-table and the conveyors for depositirg lthe gravel or other material upon op-A posite sides of the track. Fig. 5 is a vertical transverse sectional View of the apparatus. Fig. is a plan view of one of the eonvevers and showing the means for supporting the speetive v i'ew of one of the carriers of one of l l c endless conveyers.

Referring to the accompanying drawings for a more partiiular description of my invention, the numeral 1 designates a platform-rar of ne usual or any preferred construction, and mounted upon said platformcar is mj' unloading :u vparatus consisting of a frame 2, mounted upon rollers 3, and comprising a platform upon which is mounted an engine Consisting of a :.oiler 4- and oppositelydisposed c vlinders 5. The piston-lod 6 carries slides 7, supported in guides ti, and connec-ted to the ends of the piston-rod 6 are connecting-rods 9, thi' ends of which are pivoted to wrist-pins 10,. cajried b v disks 11, fixed to a transverse shaft 12, journaled in brackets 13 on hars forming part of the frame 2. Fixed to the shaft 12 is a crown gearwheel 14, which meshes with a similar gearwheel l5 of larger diameter, fixed to a shaft 16, journaled in a pair of oppositely-disposed brackets 17, rising from the platform. Also secured to the shaft 12 is a. bensi-gear 1 which meshes with a pinion 19, secured to' a longitudinal shaft 2J. The shaft 1G carries oppositely-disposed grooved pulleys 21, and at the outer sides of said pulleys sliding clutches 2*. are provided for throwing the grooved pulleys 21 into and out of operation. A ratchet-wheel 23, carried bv the shaft 16, is engaged by a pawl '.24 en the frame 2 for holdingv the shaft 16 and the pulleys 21 against retrograde movement until released by said awl. A sliding clutch 25 is mounted on the shaft 20 and is adapted to engage aclutch member 26, formed on the hub of a crown gear-wheel 2T, journaled on the shaft 20, said gear-wheel 27 meshing with a similar gear 28, journaled on a stub-shaft 29, secured and projecting from a turn-table 3() to be hereinafter referred to. The tear-wheel 28, as shown in Fig. 5, is in mesh with a series of gear-wheels 31, designed to operate the gearwheel 32, which a( tuates one of the conveyers, while upon the opposite side of said gearwheel ZS a series of gear-wheels 33 of Smaller diameter mesh with a gear-wheel 34 to actuate the gear-wheel 35 for operating the laterally-extending conveyer on the opposite side of the unloader. The gear-wheels 32, 34, 35, an'l 36 are journaled upon stub-shafts earried hy arms 37, pivote-d at 3S upon shafts extending through the turn-table 80 at opposite sides thereof. Sprocket-wheels 39 and IOO IIC

' pulleys 21 on the shaft 16.

40,journaled in the arms 37,ear11vsproeket chains 41 for a'tuaiing the umvever-helts 42. These eonvevrr-lals ea-zh tonsist of sprocket-chains 433, the links of which are provided with bral kers 44, to n hi-v h are secured angular (arriers 45, whi h serve to (any the material outward and deposit it at the opposite si-^les of t he t ar.

The chains 1.3 are af tuated b v means of sprorket-wlleels 46, mounted upon shafts 4T. journaled in side boards 4S, disposed at opposite sides of the tom evers 42, as shown in Fig. For tightening the (onveyers 42 the shaft 47 is mounted in sli'tling boxes 4S), mounted in guides 5t), and said boxes being adjustahle in the guides by means of bolts 51 passing through bra" kers 52. The inner ends of the wnveyers 42 are pi ovided w ith sprofket-wheels 53, mounted upon azshaft 54, journaled in the arms 3T, and the chain 43 engages the spro kei-wheels 53. Braf kets are ser ured lo the ronveyes 42, and cables 56 an` t onne( ted to the bra kets 55 and extended around grooved pulleys 5T andf, journaled in the upper portion of the turntable 30, said tables extending downward through the turn-table and passing around pulleys 5S), journaled in bratkets upon the stationarv member (30 of said turn-table, as shown in Fig. 4, said tables 5G extending rearward and being seiured to the groovehe turn-table 30 comprises a hollow metal structure provided with f bottom 61, carrying caster-wheels G2, supported on the rtat-ionarjv member G0 of the turn-table. The bottom portion 61 of the turn-tablelis provided with a circular rack 63, designed to mesh with a pinion G4 on the. shaft 20, and a clutch 55 on said shaft is adapted .to -throw the gear-wheel 64 into and out of operative connection with the circular' rack 63. lThe levers for actuating the clutches 25and 65 are omitted from the drawing, but maybe of the usual construction. In the bottom of the turn-table 30 a hollow projectingboss 66 engages a similar boss 67 on the stationary metnber 6() of the turn-table, as shown in Fig. 4. A draft-cable 68 is connected to a clevis 69 at the front of the stationary member 60 of the turn-table, as shown in Fig. 3.

A plow 70, comprising oppositely-diverging plates adapted to slide upon the platformcars and to push the contents thereoffonto the conveyors 42, is provided with a clevis 71, to which a cable 72 is secured. A

The operation of'my unloading apparatus may be described as follows: M v unloader ma)v be carried upon the rea-r platform-car 1 of the train and when the dirt or gravel has been taken to the place of discharge the locomotive of the train may be uncoupled from said train and the cables GS and 72 Amay be connected to said locomotive. As the locomotive moves forward it carries the plow t and the unloading mechanism from one car l to the other, and as the plow moves forward it pushes the contents of the platform-ear onto the eonvcvers 42, and said eonvtrers deposit the material at the opposite sides of the track, as will'be understood, the unloading mechanism being operated b v means of the engine 4 Should it be desired to deposit the dirt or gravel upon one side. of the track at some distance therefrom and upon the other side close to the track, one of the clutches 22 may be thrown into operation to operate one of the cables .36 to elevate one of the convevers 42. Yhen it is desired to thr w both of the convevers 42 out of operation, as when moving from place to place, both of the clutches 22 are thrown into operative connection 'with the groovcd pulleys 21, and t-he convevers 42 arc drawn npwa rd, and a further revolution of the shaft 16 will move the arms 37 upon their pivotal points 3S to throw the upper portions of said arms 37 downward within the turn-table to the position shown in Fig. 1. The clutchmembers 65 are enga Yfed when it is desired to throw the gear-wheel 64 into mesh with the xcircular rack G3 for turning the conveyors into alinement with the cars, as shown in Fig. 1. 'hen in this condition, the plow 70 and the unloading mechanism may be carried forward from car to car to unload the contents upon opposite sides of the track contiguous thereto, or when the mechanism is in this condition it tav be thrown ont of operation and the unloaded ears counled up to the locomotive and the cables 5S and 72 uneoupled to return for another load. Stops T3, carried bv the arms` 37 at their upper ends, serve to limit the downward movement of said arms.

From the foregoing it will be obvious that my unloading apparatus may be used to advantage in discharging gravel, sand, or dirt either at a distance from the sides of a train or contiguous to the track.

My apparatus operates eliiciently and will unload aA train quickly and can be readily car- 5 ried from place to place whenever required.

Having thus described the invention, what I claim is- 1.
